The Siren Board

I am preparing a list of where all the decots went originally and were they are now and what happened to some of them soon

The production Red Arrows' volume rating goes anywhere between 120 and 128 decibels at 100 feet depending on size and number of blades, very impressive for such small sirens.

Wow, that's nuts!! The Decots never went beyond fifteen horsepower, did they?

They usually ranged from 1 1/2, 3, 5, and 12 horsepower however a number of sirens had their motors changed over the years. As each Red Arrow was built by hand, no two sirens were 100% identical.

The later Decot Engineering sirens also varied considerately in profile however they bore motors no larger than 10 or 12 horsepower. Had it not been for Civil Defense's preference for more showy sirens, the Decot or something similar to it would probably still be in production.

30 day free trial?

Yes - Mr. Decot ensured that every customer was happy with their Red Arrow siren, no "defective" sirens were to be sold.

He also had a testing chamber pit beneath his machine works where he tested each siren to ensure it didn't explode when operated.

You bet they did! My friend Bill Nagler from WI personally knew some of the family members related to Ted Decot. Apparently Ted did destructive testing in a pit in the floor of the shop and actually managed to blow one up with a gas motor as a prime mover. He wanted to see how fast they could get that thing going before centrifugal forces caused it to fly apart. Bill also has a list of locations where the vast majority of Decots were installed. I think you would get a kick out of talking to him.

I've spoken to Bill on many occasions, although that was years ago. He had lots of great information regarding the Red Arrow sirens.
He also did a good job renovating Prairie du Sac's Red Arrow siren. It originally came from the city of Verona. The pole mount setup is very clever - most of these sirens were originally mounted on roof tops or towers.

Here are 2 videos of the Decot in Prairie Du Sac, WI.

Is this the Decot you were talking about? The video quality isn't the best but you can still see it. Are there any photos of this siren SuperBanshee?

He probably saw this video:

If you look in the description, it says it was filmed in Prarie du Sac, WI.
